Have a Remington 700 that you're looking to re-barrel? Whether you've got a worn-out factory barrel or want a new caliber, changing out a Remington 700 barrel always meant a trip to the gunsmith, but those days are gone! Thanks to the International Barrels Pre-Fit Barrel System, you can perform the same barrel-change job safely and easily at home. Each International Barrels Pre-Fit Remington 700 pre-fit precision barrel is constructed with a barrel-nut system that can be threaded onto your action right at home. Once the barrel is threaded into place, simply check its positioning with a set of headspace gauges and then tighten the barrel nut down to its proper torque settings. Then you're done! The easy attachment system of these International Barrels Pre-Fit Barrels isn't all you're getting. These gun barrels are button-rifled and are made to precision tolerances, double-checked at every step along the way. The barrels are made using the company's Medium contour, which features a straight taper from the breech to the muzzle. Each barrel is threaded with 5/8-24 TPI muzzle threads. The company warns that some stocks may need to be inlet to allow clearance for the barrel nut.
